Abstract

The most common cause of childhood obstructive sleep apnea syndrome (OSAS) is adenotonsillar hypertrophy. Aside from nocturnal symptoms, children with OSAS may present with lower school performance, behavioral disorder, cardiovascular complications and failure to thrive. First-line treatment is adenotonsillectomy; however, residual OSAS on postoperative polygraphy is reported in 20% to 40% of cases. In well-selected cases, orthodontic treatment can play an important role in the management of light to moderate childhood OSAS or residual OSAS after surgery, using growth activators or oral mandibular advancement appliances, rapid maxillary expansion and orofacial rehabilitation. Nevertheless, clinical studies with a high level of evidence of efficacy are lacking. To illustrate therapeutic sequences that may include an orthodontic phase, we present clinical cases encountered in our multidisciplinary outpatients clinic.
